When selecting cold shrink cable accessories, it's crucial to match the internal connector to the cable conductor material.Copper conductors require connectors with high clamping force to ensure a stable connection.Aluminum conductors (which are softer and more susceptible to oxidation) require specialized alloy connectors with oxidation resistance or a serrated surface.When selecting cold shrink cable accessories, verify the conductor material compatibility on the accessory datasheet to ensure a safe and reliable installation.
